Objective To explore the relationship between serum HBV DNA level , expression of PD-1 on CTL and liver functions in patients with hepatitis B virus cirrhosis. Methods 109 HBV hepatic cirrhosis patients with , HBV DNA positive , HBeAg positive and HLA-A2 positive were divided into two groups according to their HBV DNA levels,52 cases in group A, HBV DNA 2-4 log10 copies/mL, 57cases in group B, HBV DNA 5-7 log10 copies/mL , differences of HBV specific CTL surface PD-1 expressions , HBV specific CTL levels and liver functions were compared between two groups. Results HBV specific CTL surface PD-1 expressions of group A were lower than that of group B (t = 11.101, P < 0.01), HBV specific CTL levels of group A were higher than that of group B (t = 24.424, P < 0.01), ALT of group A were lower than that of group B (t = 2.652, P < 0.01), ALB of group A were higher than that of group B (t = 2.347, P < 0.05). Child-pugh rating, grade C of group A was lower than that of group B (χ2= 4.262,P < 0.05). Conclusions HBV specific CTL surface PD-1 expression levels were higher in those hepatic cirrhosis patients with , high level of serum HBV DNA, and HBV specific CTL levels were lower, liver functions damage were much serious. So, lower HBV DNA levels , lower HBV specific CTL surface PD-1 expression levels and higher HBV specific CTL levels can product relatively good effect of anti-viral treatment.

Objective: To study the relationship between plasma NT-ProBNP level and the severity of coronary artery lesions including left anterior descending (LAD) involvement in acute ST-elevation myocardial infarction (STEMI) patients with normal left ventricular ejection fraction (LVEF) while without diastolic heart failure. Methods: A total of 280 qualiifed patients were collected, plasma NT-proBNP level was examined in all patients within 24-hour of admission. The patients were divided into 3 sets of groups. By Gensini score system: Gensini score<30 group, n=94, Gensini score (30-60) group,n=87 and Gensini score>60 group,n=99; by the number of coronary branch lesions: Single branch group,n=78, Double branch group,n=105 and Triple branch group,n=97; by LAD condition: Criminal LAD group,n=146 and Non-criminal LAD group,n=134. Relevant comparison was conducted in all patients. Results: Plasma NT-proBNP level in Gensini score>60 group was higher than the other 2 Gensini groups, it was higher in Gensini score (30-60) group than Gensini score<30 group; the more branches were involved, the higher NT-proBNP were found (1176.70±492.50) pg/ml vs (608.70±331.20) pg/ml vs (336.90±176.70) pg/ml; NT-proBNP was higher in Criminal LAD group than Non-criminal LAD group (1199.40±725.00) pg/ml vs (607.40±244.20) pg/ml, allP<0.05. Pearson correlation analysis showed that NT-proBNP was positively related to Gensini score (r=0.278,P<0.05). Conclusion: Plasma NT-proBNP level was positively related to severity of coronary lesions, it had certain predictivevalue for triple vessel disease and criminal LAD; routine NT-proBNP examination was helpful for risk stratiifcation and clinical treatment in acute STEMI patients.

Objective Differentiation of breast fibroadenoma from breast cancer is of great importance. The purpose of the ar-ticle was to evaluate the diagnostic efficacy of magnetic resonance imaging(MRI) in the differentiation of breast fibroadenoma from breast cancer in DCE-TIC ( dynamic contrast enchancement-time intensity curve) platform type ( typeⅡ) . Methods Between March 2014 and May 2016, 64 patients were included in our study, 19 patients with breast fibroadenoma and 45 patients with breast cancer. All the patients underwent DCE-MRI ( dynamic contrast-enhanced magnetic resonance imaging) examination before operation. Morpho-logic characteristics, hemodynamic characteristics, EER ( early enhancement rate) and ADC ( apparent diffusion coefficient) values were calculated and statistically compared. Results Among 19 cases of breast fibroadenoma, 9 cases were round or ovoid, 8 cases are lobulated, 2 cases were irregular, 15 cases with clear boundary, 14 cases in mammary gland vascular enlargement, 2 cases of slowinflows, 4 cases of moderate inflows, 13 cases of rapid inflows, and the average ADC value was ( 1. 47 ± 0. 38) × 10-3 mm2/s. Low signal separation present in 11 lesions of fibroadenoma. Among the 45 cases of breast cancer, 17 cases were round or ovoid, 7 cases were lobulat-ed, 21 cases were irregular, 11 cases with clear boundary, 38 cases of mammary gland vascular enlargement, 1 case of slow inflows, 5 ca-ses of moderate inflows, 39 cases of rapid inflows, and the averageADC values was (0.98±0.40)×10-3mm2/s. The shape, (χ2=9.176), margin (χ2=16.452), EER(χ2=18.489) and ADC between breast fibroadenoma and breast cancer were of significantly difference. No significant difference was found in the increased and enlarged blood vessels. The success of ADC values in differentation of breast fibroadenoma from breast cancer was statistically significant( P<0.001), and the area under the curve(AUC)of the ROC, sensitivity and specificity of VE were 94.7% and 71.1%. Conclusion Breast fibroadenoma are in fast inflows in the early phase on the DCE-MRI, and there are differences in morphologic characteristics and mass enhancement ways between patients with breast fibroadenoma and breast cancer. Morphologic characteristics combined with inter-nal low signal separation contribute to the differentiation of breast fibroadenoma from breast cancer.
